We present our results of investigation, adjustment and measuring of the parameters of laboratory prototypes of the analog processing signal and secondary power supply units for Background Particle Detector of the Polish-Ukrainian X-ray spectrophotometer ChemiX for the interplanetary “Interhelioprobe” mission. We describe the laboratory benches designed, manufactured and tested for controlling the analog module parameters and for investigating the characteristics of small-size organic and inorganic scintillation detectors. The functional block diagram of the pilot model of digital signal processing and information data streaming based on ProASIC3E М1А3РЕ1500 FPGA is presented. We also present the results of the BPD digital module test project prototype simulation using the ModelISim Micrоsemi ME 10.2c program simulator
